Since only a modest improvement in battery lifetime is expected in the next few years, energy conservation is raised as a key factor of the design of mobile devices. In view of th...
Transmit beamforming is an energy-efficient wireless communication technique that allows a transmitter with two or more antennas to focus its bandpass signal in an intended directi...
In this paper, we present a new "spatiotemporal multicast", called a "mobicast", protocol for supporting applications which require spatiotemporal coordination...
This paper addresses the problem of tracking multiple targets using a network of communicating robots and stationary sensors. We introduce a Region-based Approach which controls r...
The tremendous popularity of wireless systems in recent years has led to the commoditization of RF transceivers (radios) whose prices have fallen dramatically. The lower cost allo...
